Running only if something is after me

Rock wall climbing would be okay, just don't know if I have that type of body strength now. Plus don't want to do anything really I'm 55 and after all the years of abuse on the body I'm in pain most of the time. Playing hard takes it's toll. Just staying inside the house is okay with me. I only go out to the store when it's late and less people.
Those jobs themselves were not trauma in the written form, but adding in the death's, suicides, mutilated bodies, dead children, being shot at, not knowing when you left home to go to work if you would be back or not wears on you. That's just a small part of this issue though.
